Abstract The SARS-CoV-2 Delta variant is currently the dominant circulating strain in the
world. Uncovering the structural basis of the enhanced transmission and altered immune …

Following the initial surges of the Alpha (B. 1.1. 7) and the Beta (B. 1.351) variants, a more
infectious Delta variant (B. 1.617. 2) is now surging, further deepening the health crises …

Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) variants continue to
emerge during the global pandemic and may facilitate escape from current antibody …

Abstract The Delta and Kappa variants of SARS-CoV-2 co-emerged in India in late 2020,
with the Delta variant underlying the resurgence of COVID-19, even in countries with high …

Background Emerged mutations can be attributed to increased transmissibility of the B.
1.617 and B. 1.36 Indian delta variants of SARS‐CoV‐2, most notably substitutions …

The new SARS-CoV-2 variant of concern “Omicron” was recently spotted in South Africa and
spread quickly around the world due to its enhanced transmissibility. The variant became …

Abstract SARS-CoV-2 recognizes, via its spike receptor-binding domain (S-RBD), human
angiotensin-converting enzyme 2 (ACE2) to initiate infection. Ecto-domain protein of ACE2 …

The emergence of SARS-CoV-2 Kappa and Beta variants with enhanced transmissibility
and resistance to neutralizing antibodies has created new challenges for the control of the …

Summary The SARS-CoV-2 spike (S) protein variant D614G supplanted the ancestral virus
worldwide, reaching near fixation in a matter of months. Here we show that D614G was …

Recent waves of COVID-19 correlate with the emergence of the Delta and the Omicron
variant. We report that the Spike trimer acts as a highly dynamic molecular caliper, thereby …
